Traffic Signal Design Software

LinSig

LinSig is our flagship product and is a comprehensive design and modelling package
for traffic signal junctions either individually or in a network of several junctions. LinSig has been used throughout
the UK since the mid 1980s and has consistently been the most widely used signal design software in the UK for over
20 years. Over this period LinSig has been extensively developed to stay at the forefront of traffic signal modelling.

The current version of LinSig is Version 3.2 which was released in mid 2012.
